Why do people complain about LeBlanc's tether range?
Just wondering.. When Morg/Lux/Xerath, etc hit you with their skillshot, you immediately take all of the damage and you're immediately CC'd. With LB's tether, she not only has to hit you but also has to stay in range until it procs. If the ADC has a support or literally any other person standing anywhere near them, the LB can't wait the 1.5s and will have to back off. If that were a morg/xerath/lux, you would be CC'd and likely dead immediately after being stunned.
LB has one of the only CC/tethers that is delayed long enough to still give you a chance to defend the person being chained, or just flash over a wall yourself and break the tether, if you already made the mistake of getting hit by the chain in the first place.
